He rite te kiriata waikura anodic o ngā wāhanga koranu konumohe waka ki tētahi paparanga pukupuku i runga i tō rātou mata. Ka hangaia he paparanga tiaki matotoru i runga i te mata koranu konumohe, ka whakarei ake i te ātete ki te waikura o ngā wāhanga, ka roa ake hoki te ora o te mahi. I taua wā, he pakeke te kiriata waikura, ka taea te whakapai ake i te ātete ki te kakahu o te mata koranu konumohe.
Ko te kiriata waikura anodic o te koranu konumohe he āhua iti te matotoru me te āhua teitei te pakeke. Me whiriwhiri ngā taputapu whakamātautau e tika ana mō te pakeke iti hei karo i te kino o te paparanga kiriata e te indenter. Nō reira, ka tūtohu mātou kia whakamahia he whakamātautau pakeke Vickers iti me te kaha whakamātautau o te 0.01-1 kgf hei whakamātautau i tōna pakeke me te matotoru. I mua i te whakamātautau pakeke Vickers, me hanga te mea mahi hei whakamātautau hei tauira. Ko te taputapu e hiahiatia ana he mīhini whakairi whakarewa (ka taea te waiho i tēnei taahiraa mēnā he rua ngā mata papatahi o te mea mahi) hei whakairi i te mea mahi ki roto i te tauira me ngā mata papatahi e rua, kātahi ka whakamahia he mīhini huri me te whakakanapa whakarewa hei huri me te whakakanapa i te tauira kia tae rā anō ki te mata kanapa. Ko te mīhini whakairi me te mīhini huri me te whakakanapa e whakaatuhia ana i te pikitia i raro nei:
1. Ngā Hipanga Whakarite Tauira (E pā ana ki te Whakamātautau Pakeke me te Matotoru)
1.1 Te Whakamātautau: Tapahia he tauira he 10mm × 10mm × 5mm te rahi mai i te wāhanga hei whakamātautau (kaua e pā ki te wāhi kukū ahotea o te wāhanga), ā, kia rite te mata whakamātautau ki te mata taketake o te kiriata waikura.
1.2 Te Whakamaunga: Whakamaua te tauira ki te rauemi whakamau wera (hei tauira, te kapia epoxy), kia kitea te mata kiriata waikura me te wāhanga whakawhiti (me whakamātau te wāhanga whakawhiti mō te whakamātautau matotoru) hei ārai i te rerekētanga o te tauira i te wā e huri ana.
1.3 Te Huri me te Whakakanapa: Tuatahi, mahihia te huri mākū taahiraa-i-te-taahiraa ki ngā pepa kirikiri 400#, 800#, me te 1200#. Kātahi ka whakakanapahia ki ngā whakapiri whakakanapa taimana 1μm me te 0.5μm. Hei whakamutunga, kia mārama te kitea o te hononga i waenga i te kiriata waikura me te papa (ka whakamahia te wāhanga whakawhiti hei tirotiro i te matotoru).
2. Tikanga Whakamātautau: Tikanga Vickers Microhardness (HV)
2.1 Mātāpono Matua: Whakamahia he kōhao piramita taimana hei tāpiri i tētahi kawenga iti (te nuinga o te wā 50-500g) ki te mata kiriata hei hanga kōhao, ka tatau i te pakeke i runga i te roa hauroki o te kōhao.
2.2 Ngā Tawhā Matua: Me ōrite te kawenga ki te matotoru o te kiriata (tīpakohia he kawenga < 100g ina iti iho te matotoru o te kiriata i te 10μm hei karo i te poka e uru ana ki te papa)
Ko te mea nui ko te whiriwhiri i tētahi kawenga e ōrite ana ki te matotoru o te kiriata, me te ārai i te kawenga nui rawa kei uru ki te kiriata waikura, ka uru atu ai te uara pakeke o te papa konumohe (he iti iho te pakeke o te papa i tērā o te kiriata waikura).
Mena he 5-20μm te matotoru o te kiriata waikura: Tīpakohia he kawenga o te 100-200g (hei tauira, 100gf, 200gf), ā, me whakahaere te whānui o te kōhao i roto i te 1/3 o te matotoru o te kiriata (hei tauira, mō te matotoru o te kiriata 10μm, ko te hauroki kōhao ≤ 3.3μm).
Mena he iti iho i te 5μm te matotoru o te kiriata waikura (kiriata tino angiangi): Kōwhiria he kawenga kei raro iho i te 50g (hei tauira, 50gf), ā, me whakamahi he karu arotahi whakanui-teitei (40x, neke atu rānei) hei tirotiro i te kōhao kia kore ai e uru.
I te wā e whakahaere ana i tētahi whakamātautau pakeke, ka tirohia e mātou te paerewa: ISO 10074:2021 “Whakatakotoranga mō ngā Paninga Waikura Anodic Pakari i runga i te Konumohe me te Konumohe Alloys”, e whakamārama ana i ngā kaha whakamātautau me ngā awhe pakeke hei whakamahi ina ine i ngā momo paninga waikura me te whakamahi i tētahi taputapu whakamātautau pakeke Vickers moroiti. Kei te ripanga i raro nei ngā taipitopito taipitopito:
Ripanga: Ngā uara whakaae mō te whakamātautau pakeke iti a Vickers
| Koranu | Te pakeketanga iti / HV0.05 |
| Akomanga 1 | 400 |
| Akomanga 2(a) | 250 |
| Akomanga 2(b) | 300 |
| Akomanga 3(a) | 250 |
| Akomanga 3(b) | Kia whakaaetia |
Kia mōhio: Mō ngā kiriata waikura he nui ake i te 50 μm te matotoru, he iti noa iho ō rātou uara pakeke moroiti, inā koa te paparanga o waho o te kiriata.
2.3 Ngā Whakatūpato:
Mō te wāhanga kotahi, me ine kia 3 ngā pūwāhi ki ia o ngā wāhi rerekē e 3, ā, ko te uara toharite o ngā pūwāhi raraunga e 9 me tango hei mārō whakamutunga hei karo i te pānga o ngā hapa kiriata ā-rohe ki ngā hua.
Mena ka puta he "ngatata" he "atanga pōuri" rānei i te taha o te kōhao, he tohu tēnei kua nui rawa te kawenga, ā, kua uru ki roto i te paparanga kiriata. Me whakaiti te kawenga, ā, me whakahaere anō te whakamātautau.
